I hope you can help me. I have the following problem: I have a graph (x-axis, y-axis) in image format and I can not build it again, I would like to know if it is possible that from that image I can give them the values, I mean, I would like to know if there is any program to coordinate a graph previously made and that is in image format.
An example, if I have this image:
what I want to know is if there's any program that gives you the values that are coordinated on that image.
Thanks!
